Just thought I’d second what Zane said about efax.com. I’ve been
using the free service for about six months, and it’s proven to be
reliable for me. The only (very minor) problem I run into is that
people sometimes find it confusing that my fax number has a different
area code than my telephone number. You can avoid this problem by
signing up for their pay service, which is something like $5 a month,
and allows you to select a local phone number rather than accepting a
randomly assigned one.
At this point, I’d even gladly pay the $5 a month if they ever stop
offering the free service, since it neatly solved my messy problem of
how to handle unexpected faxes. I really didn’t want to spend the
money to put in a dedicated fax line and buy a fax machine for the
handful of faxes I receive over the course of a year, and I was sick
and tired of trying to get my computer fax software up fast enough to
answer the phone when I picked up the line and got "beep,beep,beep"
on the other end! Efax gets my nod, as well!
